3 Claims. I'(Cl. 248-4243) This linvention ,relatesito a Ashelf J-support. Ille .essential parts comprise a longitudinal member which in its preferred construction :is embraced fby .a telescoping extension. 'Ilhis member is herein after termed a brace support. Another longitudinal member, which is used to hold the brace support, 'and therefore yadapted for wall mounting notably lengthwise in vertical position; hereafter this member is referred to as `rail holder. The novel way of assembling the brace support "and `the rail 'holder in position fou use 'as a Ishelf lsupport is accomplished by a rotational movement` after the 'brace support has been with its supporting end inserted into the rail holder in an oblique position in upward direction of one quarter turn and `then moved downward linto its horizontal position. After such -yassembling the brace support may again be removed reversing its movements for assembling it with the rail holder. The brace support may be assembled with the rail holder at various different heights from the floor. A modified construction of the brace support permits xof `assembling it with the rail support at an oblique condition in downward direction therewith. For the support of a shelf two brace supports and rail holders are used. The shelf supports are suitable for the use to display .goods in show windows.

Various other features of this invention will be apparent from the specification and the drawing, in which:

Fig. l is a side elevational view, partly in section, of a shelf support embodiment comprising a shelf consisting of glass.

Fig. 2 is .fa sectional view according to line lI-ll in Figure 1.

Fig. 3 is a plan w'ew, partly in section, of the shelf support showing the rail holder in horizontal section.

Fig. 4 is `a fragmentary elevational view that shows the brace support at an oblique angle to the rail holder to detaeh it from the latter.

Fig. 5 is a fragmentary plan view, partly in section, that shows the brace support in the position after its rotation of 1A turn, when it is in position to be removed fuom the rail holder.

Fig. 6 is a side elevational view partly in section, of a modified shelf support with a wooden shelf.

Fig. 7 is a side elevational view lof a further modiiied shelf suppont in oblique position of the brace support.

The shelf support comprises a rail holder 1 and at least one brace support 2, which is displaceable thereon in vertical direction. In case there are several brace supports, lone above .the other, attached to the rail holder the spacings between them may be changed as desired. The rail holder 1 is of mainly U-shaped profile. Both longitudinal edges 3 of the rail are lbent towards each other, forming thereby a slot 4. The web or back lof the nail holder is provided with holes 5 equally spaced from each other. The web of the rail holder comprises lscrew holes for its fastening to a vertical wall. The brace support 2 includes a guide portion 2a and a bracing portion 2b. 'Ihe supported inner end of the brace support is forked. The forked portion engages the inner hollow 2,883,137 Patented Apr. 21., .11959 ice space of `the rail `holder 1. The upper shank 7 of Athe forkedportion extendslat an oblique angle upward. The shank 7 is `formed at its end witha trunnionorlug 7a and a stud or tenon7b. The Tlower shank `of the vforked end of the brace support has a stud 8b. The studs 7b `fanilStr are `spaced from `each other `at fexactly the :same 4distances as the holes 5. Both studs 7b `and ASfb engageltworholes :5. At loading `of the brace support 2 the shank 8 `is `hiassed towards the web 4or back `of 'the rail holder 1. In that the lug 8b engages a `hole '5 the height Aof the `brace sup.- piort is definitely determined. The .lug 7a :is .held by the edges 3 of the rail holder 1. iUpon` the .guide portion Lila of the brace support v2 Ia :telescoping` extension 2d :is `Ydisposed, itis used to support a glassplate 9. Theiportions 2c and 2d are of U-type profile, its flanges having` bent edges directed towards each other to `embrace :theguide portion `2a of the brace support 2. The `telescoping portion 2d may be extended to suit the width of the shelf, and i-t is Asecured by means of a `locking screw 10. The locking screw 10 extends from underneath the iguide portion 2d upward, Iand at tightening the telescoping portion 2d is being secured to the guide portion 2a. The telescoping portion 2d is provided with an upward extension :I1 to fix the shelf 9. When theheight tof the shelf from the iioor is to he changed the `shelf 9 is removed, whereupon the brace `suppont may be detached from the rail holder. The rail holder may be removed in that it is `pivoted 11pwardly into the position shown in Fig. 4, when the upper shank 7 is moved into the .horizontal position, whereby the lower shank 8 is moved out of the rail holder; in this position the brace support is rotated about the axis Iof 'the shank 7 for 1A turn, as revealed by a comparison between Figs. 3 and 5. Then the brace support may be moved away from the rail holder (see arrow b) because .the lug 7a is then set parallel to the slot 4 of the .rail holder. The brace suppont may then be inserted at a different height from the iloror into the rail holder 1. By `a rotation in opposite direction of 1A turn the bnace support is then bnought back into the position where the lower shank 8 is directed downward and the lug 7a set crosswise to the direction of the slot 4 of the rail holder 1. After this the brace support may be returned into the horizontal position ready to take the glass plate 9. Occasional 'dislocation of the brace holder for instance by upward movement of its louter end is not possible, because ythe brace support is secured -by means of the lug 7a against movement out of the rail holder and by means of the stud 7b against downward movement. To set the brace support quickly at the desired height the holes 5 may be numbered. Such numbering may lbe marked upon the rail holder itself. In case the shelf 9a is of wood the telescoping extension is then provided with counter sunk holes for flat head wood screws 13. In this case `an extension 11 as shown in Figure l is not necessary. Figure 7 shows a modified embodiment 4of a shelf support according to this invention. 'In this case the brace support consists of two parts 2e and 2c. The part 2e comprises the orked portion 7, 8, which engages the rail holder 1. The parts 2c and 2a are journaled on the pivot pin 1.4, and contain the telescoping extension 2d. This pant 2d embraces the guide part 2a. A locking screw 10 is used to secure the telescoping extension 2d to the guide part 2a, in any desired position. The pivotable part 2c is formed with la. lug 15 extending `downward which is provided with a set screw 16 placed to abut the part 2e of the brace support. The set screw can be adjusted to provide for any oblique position and also for the horizontal position of the brace support. To secure the shelf such as a glass plate 9 upon the obliquely positioned brace support an extension 11 is used to secure a rail 11a which is fixed by means of the glass shelf 9 itself.
